The recaptcha code (or text code) i have set in all two step. User registration is possible only in the last step.
I don't have modify config module to choose where to display security code.
I had many spam users, in this mode now, user spam do not solve the second security code. In the two year in this mode i have 0 spam users.
Is a good idea to choose where apply security code, in first, second or both.
Sorry for my english.
